The plot average is the value we run statistics on, whether that means building a regression or running an ANOVA. I've recently seen a lot of my fellow grad students averaging measurements by… Continue reading Averaging Plot Data in R→

Machine learning algorithms are cool because the can handle continuous and categorical variables and have few assumptions about data distribution. As the name machine learning would imply, it's a highly automated process. Sometimes they take a while to compute, but the computer can be unsupervised during that time. One machine learning algorithm I use in… Continue reading Random Forest→

Firstly, it's written in plain English. There's not a single equation in it, and the whole paper is only 3 pages. Secondly, and probably more importantly, it… Continue reading Basic Statistics Fact Sheet→
